Unformatted text preview: relative acceleration). 3. You are asked by the local ASCE professional chapter to devise seismic response spectras for inclusion in the local structural design codes. Assuming the ground motion provided in the previous problem is a very common ground motion for the Ann Arbor area (essentially the 1,000 year seismic event – very rare), please find a SDOF Response Spectra (maximum relative displacement versus natural frequency) for the following damping ratio: (a) ξ = 0.05 Again, to discretize the ground motion, take your time step to be 0.1 second and the total time duration as 5 seconds. When plotting the response spectra, please ensure your axes are loglog and find the curve for f = 0.2 to 4 Hz in increments of 0.1 Hz....
